Abstract
trata-se de um processo multiestágio para a preparação de um concentrado de metais, metais raros e metais de terras raras a partir de resíduos de produção de alumina por processo bayer (lama vermelha), ou a partir de materiais com uma composição química similar à lama vermelha, e de um processo multiestágio para separar os elementos de interesse, transformá-los em produtos simples para serem reutilizados no processo bayer e/ou enviá-los para respectivos mercados de referência. a única figura anexa mostra o diagrama de blocos simplificado da invenção, em termos de sua definição mais extensa.This is a multistage process for the preparation of a metal, rare metal and rare earth metal concentrate from bayer (red mud) process alumina production residues, or from materials with a chemical composition similar to red mud, and a multistage process to separate the elements of interest, turn them into simple products to be reused in the bayer process and / or send them to their reference markets. The only accompanying figure shows the simplified block diagram of the invention in terms of its broadest definition.
